I like to think of myself as an advanced computer user, and I'm the guy friends and family always go to when they need help, but I'n not really *that* advanced. I downloaded the x41zc package and read the readme and I have no idea what to do with it.

I'm trying to install it on Yard, which has a brand new GT630 in it that has never done any Boinc work. The machine has never had optimized apps before. I no longer want the CPU to crunch, just the GPU.

Where do I put the files? What do I need in my app_info? Anything else that I don't even know enough to ask?DavidSitting on my butt while others boldly go,

Unzip the Jason package into default boinc folder
C:\ProgramData\BOINC\projects\setiathome.berkeley.edu
rename this file MBCuda.aistub and rename it app_info.xml
and that will get you started for doing gpu only work.
Be sure to untick cpu work in your seti account page at setie@home web site.

I didn't wait for an answer, but went ahead and did it in the long folder path I asked about... and then forgot to rename the file to app_info.xml before I unsuspended all activity. So now I have 16 tasks for the standard app. I also have 10 tasks for Einstein... and one of them is already running HP. I'll let it run like this at least overnight before I go to the E@H site and change the prefs to allow 2 at once.

I changed the file and restarted Boinc Manager and it read the file, so I think I'm good there.

If I understand something I read somewhere correctly, those 16 standard app tasks will all error out. Should I abort them and try again with the new app?

The Nvidia manager was saying I had Cuda 4.2, so that was the package I downloaded, but now the Boinc startup messages say I have Cuda version 5000, so should I download the 5.0 app and install that over the 4.2?DavidSitting on my butt while others boldly go,

No, you're running an app_info now, so those tasks will be completed by the app specified in the app_info (the website stats will say something different through),
you could always reset the project and get those tasks resent as anonymous platform tasks, report any completed tasks first!!

It probably doesn't matter eithier way, i'd do some tasks with the Cuda42 app, note down their times and angle rangles, then try the Cuda5 app, and compare.

Sounds like it's not worth the effort.

Well, I probably have to wait for a bunch of Einsteins to get done first. They're all due on 1/6, whereas the Setis are due on 2/8 and 2/13. But if I don't do it now, I may never do it.DavidSitting on my butt while others boldly go,

Okay, the 5.5 hour Einsteins all finished in 1:50. The first 48 hour Seti finished in 39 seconds, but the next took 46:46. Then a bunch of nearly 46 hour Setis took 33 minutes. At some point it reported the Einsteins and got a couple more, which are now running HP but with (slightly) shorter estimates.

Another question: does the command to run 2 Seti units at once on the GPU go in the app_info.xml? How is that worded exactly? (I suppose I could look in my i7's app_info.)DavidSitting on my butt while others boldly go,

To run 2 wu change all <count>1</count to <count>.5</count> if you have more than 767 mb of vram such as 1gb vram you can change to <count>.3</count> and it will do 3 wu in your app_info.xml file.

I found running 3 at time with 1GB OK, untill you start using other applications that make a fair amount of use of the Video RAM. Then everything comes to a grinding halt.
If you don't use the system for anything other than crunching then 3 at a time with 1GB of VRAM is OK, otherwise i'd stick with 2. If you've got more than 1GB of VRAM it's not an issue.Grant

This computer runs a radioreference.com feed and a Magic Jack besides crunching. It and my other two crunchers all share a KVM (with one empty spot). Most of the time, I only look at any of them every few days when I go downstairs to do laundry, and then if everything is okay I'll play some internet backgammon on the i7. So no, there is not much going on graphics-wise.

Does remoting in via logmein.com use any graphics resources? (I'd rather use Remote Desktop, but that shuts down GPU crunching completely.)

So far it looks like I'm saving perhaps 4 minutes per unit running two at a time. (That's for Einstein. It hasn't stopped doing that long enough for me to get a feel for how Seti units do.)DavidSitting on my butt while others boldly go,

I've downloaded CUDA-Z to figure out which version of x41zc I should be using. It says the driver dll version is 5.0 and the runtime dll version is 4.20.

So should I download the 4.2 or 5.0 version?

For your Fermi class cards ( 560ti & 470 ) I'd recommend Cuda 4.2, as there'll be some performance penalty with 5.0, as 5.0 is really Kepler class GPU oriented. For the 295 I'd go with either the 2.3 or 3.2 variant, with 2.3 being the most efficient for that generation.
